I took your data file and enclosed the dictionary in: g = Graph(<the data in the file is here>) and called the resulting file test.sage Then I used it in sage. I did it by launching Sage and doing sage: load test.sage and it created the graph in just a second or two. My guess is that with such a large text string, putting the graph in a file and then loading it would be better than trying to copy and paste the data into the command line. Alternatively, I copied and pasted your entire dictionary into a notebook cell like this: g = Graph(<your data pasted here>) and evaluated the cell and it worked fine, but I think it was a bit slower. Question for others: it seems like somewhere, sometime, I heard of a line length limit to the python command line (255 characters? I'm not sure). Has anyone else heard of such a thing? That might be what is going on here.
